In case group, 20% (2) patients have high Brinkman index, 40% (4) moderate Brinkman index, 40% (4) have mild Brinkman index, 20% (2) have high Fargerstorm score, 20% moderate Fargerstorm score, 20% (2) mild Fargerstorm score and 40% (4) haven’t addicted to nicotine. In the control group, 10% (1) have high Brinkman index, 30% (3) have moderate Brinkman index, 60% (6) have mild Brinkman index, 60% (6) have mild Fargerstorm score, 30% (3) have high Fargerstorm score and 10% (1) have moderate fargerstrom score. In both groups, 80% (8) patients have stop smoking and 20% (2) are still smoking while in anti-tuberculosis drug therapy.
